Abstract: 1387140 Bowden mechanisms; toothed gearing ROBERT BOSCH GmbH 18 Dec 1972 [21 Dec 1971] 58253/72 Headings F2K and F2Q In a drive device comprising an axially movable flexible screw-threaded, i.e. toothed cable rack guided and supported by a guide tube in a cable box and meshing in the latter with a reversible drive gear, the guide tube is releasable from the cable box to allow lateral freedom of the rack from the gear to permit axial adjustment of the cable rack relative to the gear. As shown, in an operating mechanism for a window, sliding roof or the wiping elements (12) of a motor vehicle headlamp cleaning system (10), Fig. 1 (not shown), the arrangement includes a drive unit comprising, in a housing 15, a gear-wheel 16 driven by a reversible motor via a reduction gear (both not shown) and meshing one, or as shown, two helically ribbed guided cables 13 forming flexible racks connected to the wipers (12), the cables 13 each being guided in the housing 15 by guide tube members each formed in two sections 19, 20 which may be temporarily withdrawn from the casing 15 during initial installation of the device on the motor-vehicle such that the cables 13, when assembled, i.e. introduced into the housing 15, are laterally free from mesh with the gear 16 to allow the drive unit to be fixedly mounted and the cables 13 readily connected to the wipers (12) without the need for a separate adjustment therebetween. The temporary axial freedom of the cables 13 whilst free from the gear 16 facilitates automatic adjustment of the cables relative to the gear 16 after which, when the overall assembly is complete, the cables 13 and gear 16 are brought into operative mesh by insertion of the guide member sections 19, 20 into the housing 15. Each guide member 20 has an extension 25 which spans and supports its associated cable 13 across the housing 15, the extension being cut-away to clear the toothed gear 16 &c. The guide members 19, 20 are secured to the housing by screws 27 and have serrated connections 21 over which flexible guide tubes 14 are pushed and retained. A further embodiment (Figs. 3 and 4, not shown) similarly permits lateral release of the cables 13 from the drive gear 16 to facilitate ready, i.e. automatic adjustment of the cables relative the gear during initial installation assembly of the unit on the vehicle.

Abstract: 1395690 Valves DYNAIR Ltd 18 Dec 1973 58601/73 Heading F2V A thermally actuated valve for controlling the supply of compressed air to a pneumatically operated clutch of a vehicle engine cooling fan, comprises an inlet port 36, an outlet port 35, a valve element 40 movable by a thermal actuator 27 and a pair of seals 50, 52. In use, compressed air supplied to port 36 forces the element 40 rightwardly against the action of spring 46 to a position where it disengages from the seal 50, thereby allowing the air to flow through clearance 51 to outlet port 35. Subsequent temperature rise in the engine coolant causes wax-filled actuator 27 to force the element 40 leftwards to re-engage the seal 50 and disengage the seal 52, whereby the outlet port 35 is instead communicated with a relief port 37. If the inlet pressure should fail the element 40 is forced leftwards by spring 46 independently of the actuator 27.

Transfer mechanism for a numeral register in a calculating-machine comprises a transfer tooth engaged or rendered operative by axial movement of a transfer member 13, the member being displaced between an operative and inoperative position by co-operation with two oppositely directed conical surfaces thereon of arms or projections of a pawl 14. The register shown is mounted by means of a frame 8, Figs. 1 and 4, on a movable carriage 9. The numeral wheels 18 mesh with toothed wheels 17 which are actuated by a singletoothed member 1 on a calculating-machineshaft 2 whose revolutions are to be counted. The shaft is connected through toothed gearing, including cylinder 7 which slides along wheel 6 when the carriage is shifted, with a shaft 10 which carries the transfer members 13 each having two teeth 13a, 13b for transfer during positive or negative rotations respectively of the shaft 2. The members 13 are rotatably fixed on the shaft 10 by a toothed key member 12, and during positive operations of the shaft 2 (indicated by the arrows), the shaft 10 and members 13 are rotated clockwise. At the transfer point, a tooth 18a, Fig. 4, on the numeral wheel 18 rocks the associated member 14, pivoted on shaft 15, so that its arm 14b acts on conical surface 13d, Fig. 3, to displace the corresponding member 13 to the left, Fig. 1, so that its tooth 13a registers with the wheel 17 of next higher denomination. The teeth 13a, 13b are arranged in helical curves to permit consequent transfers. The member 14 which is held in each position by a ball latch 16 is returned by a key tooth 12a, the arm 14a then acting on conical surface 13c to return the member 13. Transfer is similarly effected during negative operations.

Abstract: A burglar alarm has a series of switches 14, 16, 18 located close to each other and that are responsive to the application of a magnetic field. One of the switches 14 can be operated to terminate current flow to a sentinel current device 10 while the others 16, 18 can be operated to initiate current flow to the sentinel current device 10. The sentinel current device 10 operates to supply voltage for an alarm circuit 12 when it conducts only. Thus, in order to render the alarm ineffective, one must know how to apply a magnetic field to the terminating switch 14 only without activating any of the switches 16, 18 that initiate current flow. The switches are all located close together so that special knowledge is required to cut off supply voltage to the alarm circuit. <IMAGE>
